Roller Chain StructurePin LinkPress FitRoller LinkPress FitSlip FitWidth betweenRoller Link PlatesPinDrive Chain1. Basic StructurePress FitRollerBushingRollerDiameter PitchRoller Link PlateThree Basic DimensionsPitch, Roller Diameter and Widthbetween Roller Link Plates areknown as the “Three BasicDimensions of Roller Chain.”When these three dimensions areidentical, roller chain andsprockets are dimensionallycompatible.* Slip FitWhen the shafts and holes arefitted together, there is acontinuous loose fit. This is a fitwhere the range of tolerance forthe hole is larger than the rangeof tolerance for the shaft (pin orbushing).* Press FitWhen the shafts and holes arefitted together, there is acontinuous interference fit. This isa fit where the range of tolerancefor the hole is smaller than therange of tolerance for the shaft(pin or bushing).A-8Offset PinCotter PinSlip FitSpring clips, cotter pins andspring pins are the parts thatprevent the connecting linkplate from falling off the pin.These parts are critical in orderto maintain the originalstrength of the chain.Connecting Link PlateSpring ClipPin Link PlateSingle StrandPin LinkInner PlateOffset Link Connecting LinkRoller ChainRoller LinkMulti-Strand Pin Link(Two-strand chain shown)• PlateThe plate is the component that bears the tension placed on the chain. Usually this is a repeatedloading, sometimes accompanied by shock. Therefore, the plate must have not only great statictensile strength, but also must hold up to the dynamic forces of load and shock.• PinThe pin is subject to shearing and bending forces transmitted by the plate. At the same time, itforms a load-bearing part, together with the bushing, when the chain flexes during sprocketengagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,and also must have sufficient endurance against shock and wear.• BushingThe bushing is subject to complex forces from all parts, especially from the repetition of shockloads when the chain engages the sprocket. Therefore, the bushing needs extremely high shockresistance. In addition, the bushing forms a load-bearing part together with the pin and as suchrequires great wear resistance.• RollerThe roller is subject to impact load as it strikes the sprocket teeth during the chain engagementwith the sprocket. After engagement, the roller changes its point of contact and balance. It is heldbetween the sprocket teeth and bushing, and moves on the tooth face while receiving acompression load. Therefore, it must be resistant to wear and still have strength against shock,fatigue and compression. RS11 / 15 / 25 / 35 do not have rollers.• Roller LinkTwo bushings are press fit into two roller link plates and rollers are inserted to allow rotationaround the outside of the bushing. This is the same for single strand and multi-strand chain.• Pin Link and Inner PlateThe pin link consists of two pins that have been press fit into two pin link plates. In the case ofmulti-strand roller chain, an inner plate is added to the pin link. The inner plate is slip fit forStandard RS Roller Chain and press fit for SUPER Roller Chain.
Roller Chain Structure2. Assembly PartsRoller Chains are usually made up of a number of connected links in an endless formation, or used by fixing the chain ends, but theneed for connecting links will eventually arise. Although offset links can be used when there are an odd number of links in the roller chain,please use a design that requires an even number of links as much as possible.2.1 Connecting LinksM-type Connecting Links (Formerly: Standard Connecting Link)RS Roller ChainCotter Pin-typeClip-type Cotter Pin-type Multi-strand (2-strand shown) Spring Pin-type (RS240 only) F-type Connecting LinkClipPin Link PlatePinConnecting Link Plate(RC processing)Cotter PinPinPin Link PlateInner PlateConnectingLink PlateSpringPinPin Link PlatePin Pin PinConnecting Link PlateClipPin Link PlateConnectingLink PlateCotter PinDrive ChainChain TypePin & Connecting Link PlateFittingConnecting Link PlateFastening MethodPoints to NoteRS Roller ChainSlip FitPress FitClipCotter PinSpring PinClip / Cotter PinSpring PinT Pin• For multi-strand chain, make sure the plate with ringcoining processing is on the outer most side whenassembling.• Operating speed is indicated by the white area in theHP ratings table.• Make sure to use the chain according to the specifiedapplications on page A-90 and within the speed regionof the colored area in the HP rating tables.Lambda (Λ) RollerChainSUPER Roller ChainSUPER-H Roller ChainULTRA SUPER Roller ChainRS-HT Roller ChainSlip FitPress FitPress FitClipCotter PinSpring PinCotter PinSpring Pin• Can be used in all areas of the HP ratings tablefor Lambda Chain.• Ring coining is carried out on the connecting linkplates.• Please use the exclusive connecting links for eachchain type.• Please use the exclusive connecting link for RS-HTRoller Chain.Heavy Duty RollerChainPress FitT Pin• There are no connecting links, so use connectingpins for assembly.2.2 Offset Links1 Pitch Offset Links (OL)Single strandOffset Link PlateMulti-strand(2-strand shown)2 Pitch Offset Links (2POL)Single Strand Multi-strand (2-strand shown)1 Pitch Offset LinksWhen an OL is used, please allowfor a 20% reduction in HP ratingscompared to that of the main chainand a 35% reduction in MaximumAllowable Load.PinCotter PinOffset Link PlatePlease refer to the dimension tables for roller chain types and sizes suitable for offset links.2.2 Identical maximum allowable load as main chain…(Slip-fit connecting link and two-pitch offset link)Tsubaki ANSI Standard Roller ChainMain chain 100%Slip-fit connecting link 100%Semi Press-fit connecting link 100%Two-pitch offset link 100%One-pitch offset link 65%Pin2 Pitch Offset linksThe pin and offset link plate of a2POL is press fit and is fastenedby a rivet.
